TOOTH CONTACT

1.

Remove rear cover. Refer to 

DLN-214, "Disassembly"

.

2.

Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier.

a.

Set dummy cover shims to the right and left side bearing adjusting shims.

b.

Temporarily tighten dummy cover to gear carrier.

c.

Position dummy cover spacers to dummy cover.

d.

Tighten rear cover mounting bolts to the specified torque. Refer to 

DLN-219, "Exploded View"

.

e.

Tighten dummy cover spacer mounting bolts evenly to the specified torque.

3.

Apply red lead to drive gear.

CAUTION:

Apply red lead to both the faces of 3 to 4 gears at 4 loca-
tions evenly spaced on drive gear.

4.

Rotate drive gear back and forth several times, check drive pin-
ion gear to drive gear tooth contact.

CAUTION:

Check tooth contact on drive side and reverse side.

DRIVE PINION

Tooth Contact Judgment Guide

5.

If tooth contact is improperly adjusted, follow the procedure
below to adjust the pinion height (dimension X).

• If the tooth contact is near the face (face contact), or near the

heel (heel contact), thicken drive pinion gear adjusting shim to
move drive pinion closer to drive gear.

• If the tooth contact is near the flank (flank contact), or near the

toe (toe contact), thin drive pinion gear adjusting shim to move
drive pinion farther from drive gear.

BACKLASH

1.

Remove rear cover. Refer to 

DLN-214, "Disassembly"

.

2.

Following the procedure below, install a dummy cover set (SST: KV389L0010) to gear carrier.

a.

Set dummy cover shims to the right and left side bearing adjusting shims.

b.

Temporarily tighten dummy cover to gear carrier.

c.

Position dummy cover spacers to dummy cover.

d.

Tighten rear cover mounting bolts to the specified torque. Refer to 

DLN-219, "Exploded View"

.

e.

Tighten dummy cover spacer mounting bolts evenly to the specified torque.

3.

Fit a dial indicator to the drive gear face to measure the back-
lash.

• If the backlash is outside of the specified value, change the

thickness of side bearing adjusting shims.

Inspection After Disassembly

INFOID:0000000010288422

Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.

Standard

Backlash

: Refer to 

DLN-229, "Back-

lash"

.

When the backlash is large:

Make drive gear back adjusting shims thicker, and drive 
gear front adjusting shims thinner.

When the backlash is small:

Make drive gear back adjusting shims thinner, and 
drive gear front adjusting shims thicker.

Conditions and Measures

Hypoid gear

• If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-

essary.

• If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new 

drive gear and drive pinion as a set.

Bearing

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing is 
observed, replace as a bearing assembly (as a new set).

Side gear and Pinion mate 
gear

• If any cracks or damage on the surface of the tooth is found, replace.
• If any worn or chipped mark on the contact sides of the thrust washer is found, replace.

Side gear thrust washer and 
pinion mate thrust washer

If it is chipped (by friction), damaged, or unusually worn, replace.

DRIVE PINION

Differential case

If any wear or crack on the contact sides of the differential case is found, replace.

Companion flange

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the com-
panion flange is found, replace.
